plays a very important role in how well the
machine operates. TENNANT hydraulic fluid is
specially selected to meet the needs of TENNANT
machines.

If using a locally
−
available hydraulic fluid, the
specifications must match the TENNANT
hydraulic fluid specifications. Substitute fluids can
cause premature failure of hydraulic components.
ATTENTION!: Use of hydraulic fluids not
meeting the TENNANT hydraulic fluid
specifications listed in the table above will
void the warranty.
ATTENTION! Hydraulic components depend
on system hydraulic fluid for internal
lubrication. Malfunctions, accelerated wear,
and damage will result if dirt or other
contaminants enter the hydraulic system.
BATTERY ISOLATION BUTTON
Check operation of the Battery isolation button
daily. The machine should not start after the
button is engaged. Ensure the lock holds the
Battery isolation button down when the lock is
engaged.
BATTERY PACKS
Do not allow operators or service personnel to
connect the Tennant Programmable Smart Ion
Charger to the battery packs unless and until such
persons have attended and been certified through
the Tennant training program. See Lithium

Battery Pack Warranty.
The battery packs are designed to hold a charge
for a typical cleaning shift. Fully charge both
battery packs after each use to ensure the
machine is ready for use. Both battery packs must
be fully charged before the machine is operated.
Do not allow the battery packs to be discharged
below 15%. Never store the battery packs
uncharged (below 15%) for more than three
weeks.
ATTENTION!: Battery packs damaged as a
result of being discharged below 15% will not
be covered under warranty.
After every 450 hours of use check the condition
of battery packs. Clean dirt and debris from
battery packs as necessary.
After every 450 hours of use check the front
battery lock and rear battery lock for damage and
to ensure they operate freely.
